LIQUID-DISPENSER.

Application filed. November 26,1915. Serial No. 63,509.

To all whom it may concern:

Be it known that we, WILLIAM HENRY" JOHNSTON and HENRY JOHN VVILLIA s,citizens of the United States of America,residing at New York city, inthe State of New York, United States of America, have invented certainnew and useful Improvements in Liquid-Dispensers, of which the followingis the specification.

This invention relates to dispensing, mixing Or serving apparatus forliquids or the like and general obj ect of the inventionis to enable anexact proportioning, effective mixing and an aeration of a plurality ofliquids to be Obtained. The invention is particularly useful oreffective to the mixture of a syrup or concentrate in given proportionwith water orother suitable liquid.

In this type of apparatus it is important that exact proportion shouldbe maintained between the syrup and water, and that an 3 effectivemixture and aeration should take place before the mixed ingredients aredis charged in the formof the finished drink.

Still further object of the invention is to provide such a typeofdeviceas maybe readily combined with heating or cooling means in order thatthe drink to be served therefrom, may be hot or cold as desired.

The invention comprises, generally stated a mixing chamber, means forsupplying proportional quantities of liquids thereto, and

producing a swirling mixture therein, means for dlscharging the IIllXGdproduct under pressure in such a manner as to effect aeration. Forcomplete understanding of the invention, however, reference is made totheaccompanying specification and drawin s. In the drawings, 3

igure 1 is a sectional elevationof an embodiment of the invention.

Fig. 2 is a sectional detail through the measuring cylinders.

Fig. 3 is a plan of the measuring cylinders. i

Fig. lis a sectionalview of one form of nozzle. fl

Fig. 5 is a sectional detail" of an alternative form of nozzle.

Like characters ofreference indicate corresponding parts in all figures.

Referring to the drawings, A represents a casing adapted to contain theprincipal working parts and also to contain means for which it isheating or cooling the beverage served. In the embodlment illustratedthe device may be used as a cooler and ice maybe placed therein, the icewater being drained through a sultable outlet cook 11 B represents thecontainer for the syrup or concentrate and C the container for the waterwhich is to be mixed therewith. These so that they may be fed in uniformproportions, a barometric feeding arrangement is I SpecificationotLettersPatent. P te t N0 30,

containers are conveniently in the form of in- *verted bottles and inrder to secure uniprovided, consisting of wells 12 and 13 into which thenecks of the bottles B and G extend, the said necks extending throughthe top 14: of the casing and being supported thereby. It will beobvious, however, that other suitable means of support for the bottlesmay be provided.

From the wells 12 and 13 the liquids and syrup are adapted to pass byconduits 15 and 16 to the cylinders D and E, which are conveniently casttogetherand arranged in co- 3 axial relation as shown. The conduit 15,from the well 13, which supplies water from the container 0, leadsthrough the cooling chamber F and maybe surroundedby ice Said conduit15opens into a port part of the cylinder D. The conduit 16 therein, andmay also beextended to any desired extent in order to securetherequisite cooling.

17 in thejconstrictedneck 18 on the upper opens into the port 19 formedinthe constricted neck 20 at the top Ofthe cylinder E.

The diameters of the respective cylinders D and E correspond with theproportion in desired to mix the syrup and liquid? a Cooperating withthe cylinders are plungers G andH which in the embodiment illustratedare formed integral with each other. The smooth outer surface of theplunger G fits the smooth inner surface of; theneck 20,

while the smooth outer surface of the plunger H fits the smooth innersurface of the "neck 18. Escape of any liquid from the cylinder D isinsured by a "suitable packinlg t gland 21 at the top. of the cylinder.will be observed that asthe plungers fit the necks 18 and 19, whentheyare in innermost position 3113111111181 space will remain between theplun ers, and the walls of the cylinders, and rom these annular spaces,

. This arrangement ha's'an effect of producing a swlrling motionofliquid in the chamber K, which will thoroughly mix the constituentparts of the: liquid.

Fromtheoutlet 25, a conduit 26 leads to a discharge nozzle 27. Thisnozzle is designed. to effect aeration of the product, Which isaccomplished by forming a plurality of .fine orifices 28 in the nozzle,

- charged under pressure.

through which the mixed liquid is dis- In the form of nozzle shown inFig. 5, the fine streams from the orifices are combined by a taperingnozzle member 2,9..and" discharged through the orifice 30 in. a finestream. Should it be desired to heat the liquid instead of cooling it,an electric or other form of heater L of .well-known design may beattached to or combined with the conduit 26.

The pistons G and Hmay be operated b [any convenientmechanism. As shown,an vopera'tlng lever M'is pivoted to a bracket '31 on the casing and hasa link 32 pivoted "near the'end to the same, the opposite end of thelink being pivoted to a bracket 33 on the interior of the piston H. V

If desired a suitable-counter N may be provided; which will be operatedby the movement of'the link 32 and by which the number of drinks-servedby the dispenser may be indicated in a well-known way.

.Tonpreventtheproducing of a vacuum in thecylinder D, an air vent in theform of a msmall conduitO/maybe provided leading from the upper part ofthe cylinder.

' In operation the containerB-is filled with the syrup orconcentrateandthe container Cisfilled withsthe water, with which it is 'to-be mixed.The apparatus is designed for usewith a variety of syrups and liquids.-'I}hewaterfmay be charged with carbon dioxld or not, and the apparatusmight even .Jbe'used tomixpastes or-semi-plastic sub- --:S C

1 Thef-normal position ofthe plunger is the raised;positionshown in Fig.2. It will be "seen; that in --this' position both cylinders D LandE-willbe ,fill'ed by gravity from the containers.B and C. The barometricfeed arrangement insuresuniform, atmospheric -.pressure. 21A pressurefeed might however "be used if desired.

. Whenit isdesired to serve-a drink from I Qthe-apparatuathelever M isoperated in a .downward direction. forcing both plungers downwardly;This movement will at once .eut.ofi th mrtsaflwand. =19, preventing anyfurther flow of liquid or syrup. The continued movement will force theli uid and syrup contained in the cylinders and E through the ports 23and 24: into the mixing chamber K. Owing to the fact that the liquid andsyrup are introduced from the bottom and at one side of the mixingchamber a swirling motion will be produced therein which will effect themixing thereof.

The further downward motion of the lever will assert a. pressure on themixed liquid forcing it through the conduit 26 and discharge nozzle 27,under pressure. This will result in the production of a plurality offine streams, which immediately 011 leaving the nozzle will absorb aquantity of air, thus giving the desired aerated eilect to the drinkfinally produced.

The amountof pressure which comes from the degree of aeration may beregulated by the pressure on the lever M. It will be observed that theliquids are not only mixed under pressure; but that they are alsodischarged under pressure. Immediately on raising the plungers G and Hon the return movement of the lever M, water and syrup will flow intothe cylinders D and E under gravity.

As many changes could be made in the above constructions and manyapparently widely different embodiments of our invention, within thescope of the claims, constructed without departing from the spirit orscope thereof, it is intended that all matter contained in theaccompanying specilication and drawing shall be interpreted asillustrative and not in a limiting sense.
